CHARLES G. ANAS'I'OR, 0F VINEIiAND, NEW JERSEY, ASSIGNOR TO KIMBLE GLASS COM- PANY, OF VINELAND, NEW JERSEY, A CORPORATION OF ILLINOIS DISPMSING APPLIANCE Application filed March 17, 1933. Serial No. 661,288.

My invention relates to appliances for delivering or dispensing liquids or solids, such as powders or the like, and concerns more particularly, but not exclusively or restrictedly, devices of this character which may be used as applicators, inhalers, or similar appliances which are usually made of glass, at least in part.

Such novel and improved structures are especially useful in dispensing or applying perfume, iodine, mercurochrome, or similar liquids, or talcum powder or its equivalent.

In general, the new constimctions ordinarily comprise a main glass container or receptacle, preferably of general cylindrical form, with one end shaped to provide a discharge opening ordinarily relatively small in size, and with the other end open\ and equipped with a demountable or removable cap or closure on which is secured a glass rod equipped with a valve at its opposite or free end which controls the opening or closing of the delivery port and hence governs or regulates the discharge of the containers contents.

In order that the valve may properly and completely close the delivery port or opening without danger of breakage of any of the parts, yielding means are incorporated in the device to give an adequate amount of resiliency so that the cap or closure may be fully screwed on to the neck of the container or receptacle, with the assurance that the valve will close the port or discharge opening and without danger of injury to or breakage of any of the parts-involved.

An aim of thevinvention is to provide a structure of this generic type which is simple in construction, which performs its functions eiiiciently and satisfactorily, which can be manufactured at relatively small cost, and which is unlikely to be damaged or broken in ordinary service.

In order that those skilled in this art may fully understand the invention, both from structural and functional standpoints, in the accompanying drawing, forming a part of this specification, several desirable embodiments of the invention have been shown and they are described in detail below.

In this drawing Figure 1 is a central, longitudinal section through an applicator incorporating the new invention; and

Figures 2, 3, and 4 are similar views of different typos or styles of inhalers, each likewise embodying the invention.

Referring first to Figure l, the elongated,

hollow, generally-cylindrical, glass body 11,

which is designed and adapted to contain the supply of material to be dispensed, whether in liquid or in powdered form, has one end 12 tapered both externally and internally material is adapted to be screwed on to such neck and to close the corresponding admission op'ening'of the container completely, the cap having a central internal stud 17 projecting a short distance inside of the applicator when the cap is screwed home on the neck and also having an appropriate-compressible sealing-disc 18, such as cork, adapted to be pressed or forced firmly over the mouth of the container and to close it efficiently when the cap is in place.

The device includes also a coiled spring 19 held firmly on the stud by the contraction of the encircling convolutions of one end of the spring thereon, the opposite terminal portion of the spring being likewise attached to the end portion of a glass-rod 21 which has an enlargement 22 against which the end of the spring bears to assure proper assembly of the parts and to prevent too much of the rodextending up into the spring, a suitable space being provided between the adjacent 7 ends of the aligned parts 21 and 17 to perthe required play or movement of the The opposite end of the rod has a ground, conical valve 23 cooperating with the companion valve-seat 14,'and the rod at 24 extends beyond the valve and out through and beyond the discharge port 13.

From what precedes, it will be clear that the container having been charged with the material, liquid or powder, to be dispensed or applied, its delivery or discharge port or opening will normally be closed by the valve engaging its companion valve-seat against which it is yieldingly held by the tendency of the spring to elongate, the parts'heing designed, arranged, and assembled to accomplish this object.

If the protruding tip 24 of the rod is pushed in by pressing it on the surface to which the contents of theappliance is to be applied, the valve will be opened and a portion of such contents delivered automatically by gravity through the opening 13, and, as soon as the pressure is removed from the rod end, the valve will automatically close under the influence or action of its spring.

The cap, spring, and rod and its valve are all fastened or secured together as a unit, so that removal of the cap carries the associated parts with it, thus allowing the appliance to be readily refilled, cleaned, etc.

Also, owing to the inner conical shape of the discharge end of the device, in re-inserting the rod, its valve end is directed to correct seating position on the valve-seat.

In Figure 2 I have shown the same general principle incorporated in an inhaler.

In this case, the glass cylindrical receptacle 111 has one end 112 of conical or tapered form both internally and externally, the shape and size of its outer surface adapting it for convenient insertion in a nostril; such reduced end of the body having a ground, conical delivery-port 114.

At its opposite end, the glass container has the corresponding neck 115, cap 116, stud 117, sealing-disc 118, and air-inlet ports 120 extended through the flange portion of the cap just below the sealing-disc.

-As in the other instance, the appliance includes a coiled expansion spring 119, glassrod 121, enlargement or boss 122, and conical valve 123 co-acting with the valve-seat 114, but,'in this instance, the rod has no protruding tip corresponding to the part 24 of the applicator, because this appliance is to be used as an inhaler.

Ordinarily, the discharge-port is maintained closed by the valve responding to the action of the spring, but when it is desired to inhale some of the contents of the device, the cap is turned a small amount sufficient to open the valve and to shift the bleederholes 120, 120 to a position just beyond the end of the neck, so that they can then admit air into the inhaler.

Thereupon the inhaler is used in the ordinary way, the admission of a small amount of air through the ports 120 allowing the proper discharge of some of the contents of the receptacle into the nostril under the suction or inhaling action exerted by the user.

The modified structure of inhaler presented in Figure 3 is similar, except that a rubber or other resilient valve 223 is mounted on the end of the solnewhat-shorter glass-rod 221, such valve co-acting directly with the inner conical surface of the tapered end portion of the container 211 to open or close the terminal delivery opening 213.

A further embodiment of the invention in an inhaler is depicted in Figure 4, and in this case, the hollow glass receptacle 311 is constricted internally at 310 to hold a centrallyported rubber disc or valve member 309 fixedly in place, its valve port being designated 314, whereas the end discharge port of the container is characterized 313. a

The glass rod 321 is mounted at one end in any approved manner in the cap as in a socket 317, the opposite end of the rod having a rounded or substantially spherical valve 323 co-acting with the wall of the port 314 to open and to close the latter, depending upqp the position of the cap on the threaded nec In this case, the coiled spring is dispensed with, the inherent resiliency of the rubber disc performing the corresponding function by reason of its pliancy.

The spring or the rubber member, as the case may be, assures that the delivery valve will be properly closed when required, and it also compensates for any ordinary variations in the manufacture of the parts involved. .4

- Whereas several embodiments of the invention have been shown and described, those acquainted with this art will readily understand that the invention is not necessarily limited and confined to their particular details of construction, and various more or less radical modifications may be resorted to without departure from the heart and essence of the invention, as defined by the appended claims, and without the loss or sacrifice of anyof the material benefits and advantages {accruing from the employment of the invenion.

I claim:

1. In a dispensing appliance, the combination of a container adapted to hold the medium to be dispensed, saidcontainer having a mouth at one end and a delivery-port near its opposite end, a closure for said mouth, a resilient member in said container having a discharge-port therethrough, a rod secured to said closure, and a valve on said rod cooperating with said discharge-port, whereby the opening and closing of said port by said valve is controlled by the position of said closure.

said mouth screw-threaded on said neck, a

rod, a spring yieldingly mounting said rod on said cap, and a valve on said rod cooperating with said discharge-port, whereby the opening and closing of said port by said valve is controlled by the position of said cap.

4. The structure presented in claim 3 in which said cap has an air-inlet aperture positioned to close when the valve closes said port and to open when said valve opens said port.

5. In a dispensing appliance, the combination of a container adapted to hold the medi nm to be dispensed, said container having a mouth at one end and a discharge-port near its opposite end, a closure for said mouth, a rod, a spring yleldingly mounting said rod on said closure, and a valve on said rod cooperating with said discharge-port, whereby the opening and closing of said port by said valve is controlled by the position of said closure.

In witness whereof I have hereunto set my hand. 4
